Synthesis of 3,4-dihydropyrimidinones catalyzed by ammonium chloride or montmorillonite KSF without solvent under ultrasonic irradiation
Written by sctunisie no commentsThe condensation of aldehydes, β-ketoesters and urea catalyzed by ammonium chloride or montmorillonite KSF without solvent results dihydropyrimidinones. Under ultrasonic irradiation at room temperature, Biginelli products were obtained in higher yields with shorter reaction time.
